MACHINE FOR THE MANUFACTURE OF ASPHALTUM PIPE.

SPECIFICATION forming part of Letters Patent No. 522,946, dated July 10,1 894.

Application filed December 7, 1892. Serial No. 454,415. (No model.) l

California, have invented certain new and useful Improvements inMachines for the Man ufacture of-Asphaltum Pipe; and we do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

Ourinvention relates to anew and very useful machine for the manufactureof asphaltum pipe for general use, the description of which will behereinafter more fully set forth.

The following description fully explains'the i nature of our saidinvention and the manner in which we proceed to construct, apply and usethe same. We attain these objects by the mechanisms illustrated in theaccompanying drawings, in which- Figure l is a perspective View of themachine showing all parts of the mechanism as constructed and operatedin the manufacture of asphaltum pipe. Fig. 2 is a perspective view ofthe finishing furnace, the top of which consists of a suitable metalplate of the desired thickness and of any suitable size. To one side andon top of the plate is placed a suitable sized longitudinal tank forholding prepared asphaltum, and arranged as desired thereon is a coatingroller, and on one side of said furnace is placed and made a partthereof a frame, upon which are arranged the heated rollers connected tosteam pipes from the boiler or any other suitable device whereby theresult of heating as desired may be accomplished. Fig. 3 is aperspective View of part of the concrete screening apparatus which hangsdirectly over the metal plate or top of furnace upon which thescreenings fall, while the pipe is being rolled thereon after beingcoated. Fig. et is a side view of the three circular knives and themechanisms for operating the same, and also their relative positionswhen operated upon by the lever handie, in cutting the pipe in desiredlengths during the process of manufacture. Fig. 5 is a perspective viewof portions of the adjustable shaft, having at its lower end two or moreprojecting arms for holding and guiding the fiber bands or cloth as theycome from the spools and pass through the asphaltum mixture in the tank.Fig. Gis a perspective view of the outer end of the mandrel or core, andparts of all the mechanisms for operating the same during the process offorming and manufacturing asphaltum pipe. Fig. 7 represents the couplingends of the mandril or cores, and the manner of coupling same togetherduring the processof forming the pipe around the said core or mandrel.Fig. S represents a portion of the gear wheels carrying the feed belt,which operates and feeds the mandrels orcores during the process offorming or manufacturing asphaltum pipe. Fig. 9 represents aportion ofthe gear wheels connected to the heated rollers for operating same, infinishing asphaltum pipe.

Similarletters refer to similar parts throughout the different views.

N and O represent the pivotal joints connected to the circular knives. Pguide arms or stops for holding feed belt R` in one position whilefeeding the mandrel or cores. P2 sleeve holding and coupling the cores622. QL-Q' guide boxes for the mandrels or cores Q2 to travel throughwhile forming the asphaltum pipe. alead band near the coupling ends.` Slarge gear wheel. T smallv driving gear TOO and in which is placed anadjustable shaft V having arms L-X near the bottom thereof, and in thelower guide box V2 is a set screw W for holding said shaft in anydesired position. Y the spools or guide pulleys for feeding off anysuitable fiber or cloth Y2 Z spool or guide pulley for feeding offcontinuous strips of suitable paper Z2 as desired.

By reference to Figs. 2 and 3 itwill be seen that No. 1 is alongitudinal iron tank or kettle of suitable width and depth, andsurrounded by brick work if desired, at the bottom of which is arrangedthe furnace 2, and 3V asphaltum tank. 4- the iron top plate of the steamchest and furnace. 5 the asphaltum coating roller. 6, 7 and 8 the steamheated rollers for nisliing asphaltum pipe. 9 is the lever framepivotally constructed which operates the heated roller 8 when desired.10 steam pipes which supply steam or hot air to the cylinder rollers 6,7 and 8. 11- the gear wheels for operating rollers. 12- frame upon whichare mounted and operated the heated rollers. 13m band pulley secured tothe asphaltum coating roller. 14roperating and loose pulleys. 15- bandpulley. Connected to the screeningA wheel 16, and 17 is the long Ushaped screening trough suspended from the ceiling directly over the topplates t of the furnace l. 13 suspended hanger from the ceiling to whichis pivotally attached the lever arm 9 for operating the steam cylinderroller S.

In constructing our machine for the manufacture of asphaltum Ypipe forgeneral use, we rst construct a suitable furnace B and upon the same asuitable sized iron kettle or tank A is placed. The outer side is linedup with brick to hold the heat. Arranged on the inside of the said tankA is a stirring or agitating apparatus consisting of a paddle wheel Csecured to-the bottom end of a shaft suspended in the center of the tankA by arms DD, and on the top of this suspended shaft is secured abeveled cog wheel E, having a smaller one operating the saine which issecured to the end of the operating shaft F5 and attached to one side ofthe tank and to the ceiling, is an upright standard U to which aresecured two or more guide boxes V2 into which the adjustable shaft V isadjusted into the tank A and out of the same as desired, and held inposition by set screw W. Also to this upright standard U are securedthree or more large spools. From the lower spool Z 7 strips of anydesired width of paper are unwound upon the mandrel or cores Q2, and inlike manner are the unwoven or woven strips of burlap Y2 taken off thetwo spools Y and wound around the mandrel or core Q2 over the layer ofpaper Z2 Tlieburlap Y2 covers each seam of the paper and the last layerof burlap strip from the second burlap spool covers the last seam madeby each layer cf liber or cloth. Before this operation is beg/un,themandrel or core"Q2 is placed in position as shown in Fig. 1 and into theguide boxes Q-Q, and the feed band R is given one turn around the coreor mandrel Q2. This one turn which forms a band like around the mandrelor core, 1s then placed between the two stationaryiguide arms P-P whichhold the belt R in one position, at the same time producing a freercctilinearrotary movement of themandrel or core Q2, thus with greataccuracy keeping up the supply of cores or niandrels Q2 by coupling anew section of the core as fast as the feed belt fR requires the supply,and as each section of the core Q2 is covered or the pipe is perfectlyformed thereon, it

is run out and cut off by the circular knives Ii-K at the point ofVcoupling, when the same is uncoupled and placed in the asphaltum vat 3beside the coating roller 5, when the same is coated as desired; afterwhich the new formed pipe is removed from the vat or tank 3 onto theheated plate4, over which it is rolled while the sander pulverizedconcrete is screened down upon .it from the screenings trough 17. Afterthis process has been suitably performed and the required thickness hasbeen produced, the pipe, which continues to retain the core Q2, is thenplaced between the heated rollers 6, 7 and 8, and under a great pressureis thoroughly rolled smooth, after which it is removed and placed uponracks to harden, when the core Q27 is removed. The core can be removedat anytime, as the firstcoating of paper Z2 is wound around the coresfor the purpose of preventing any asphaltum adhering to the cores andenabling the same to beremoved freely.

The operation of forming the pipe over the cores Q2 consists in thefollowing: The ber or burlap strips of suitable width are supplied fromspools Y, passing through a pr epared mixture contained in tank A. Asuitable composition such as asphaltum, slaked lime, salt, liquidasphaltum, or crude petroleuni may be used. These ingredient-s are keptat a heat of from 350o to 420, and as these strips of fiber or burlappass from the lsaid mixture they are wound around the whirling mandrelor core Q2, which has been previously wound over by paper strips Z2, andthe process of winding the burlap strips when thoroughly soaked in themixture of asphaltum carries much of the mixture oi `material as itwinds around the core and lforms the pipe, which hardens almost as fastas applied. v Y Having thus fully described our invention, what Weclaim, and desire to secure by Letters Patent, is
